GHK-Cu (Copper Peptide)
A natural copper-carrying peptide famous in research for helping skin and tissue make more collagen and repair themselves.
What Researchers Study
GHK-Cu is a tiny three-amino-acid peptide that naturally binds to copper. It has been studied for decades because copper is important for making collagen and protecting cells from damage. When researchers add GHK-Cu to skin or connective tissue cells, they often see big changes in which genes the cells turn on or off — especially genes involved in repair and antioxidant defense.
Primary Research Applications
- Testing how much collagen skin cells produce
- Wound healing scratch tests
- Hair and skin structure research
- Looking at antioxidant and calming effects
Benefits Researchers Are Exploring (in simple terms)
- Strongly increases production of collagen and elastin (the proteins that give skin and tissue strength and elasticity) in fibroblast studies.
- Helps wounds close faster and improves the quality of the new tissue that forms.
- Appears to reset thousands of genes in aging or stressed cells toward a healthier, more youthful pattern.
- Supports the body's natural antioxidant enzymes (like SOD) by delivering copper where it is needed.
- Popular in skin remodeling, hair follicle, and anti-aging type research because the effects are broad but gentle.
Mechanisms Under Investigation
Collagen Factory Boost
It tells fibroblasts to make more type I and III collagen plus elastin in a dose-dependent way.
Gene Reset
Microarray studies show it changes the activity of thousands of genes related to repair, inflammation, and antioxidant protection.
Copper Taxi
It acts as a safe carrier that delivers copper to enzymes that need it for cross-linking collagen and fighting free radicals.
Reconstitution Reference (how to mix it for lab use)
| Common vial sizes | 50 mg and 100 mg |
| Reconstitution | Add 5 mL bacteriostatic water to a 50 mg vial = 10 mg per mL. |
| Storage | Freeze the dry powder. Copper versions can be sensitive to air and light once mixed. |
| Cell work | Most studies use 1-10 micrograms per milliliter in the culture media. |
Dosing Schedule Options from Research
Example Options Used in Studies
- Cell culture standard: 1-10 mcg per mL added to the media, often for 5-14 days continuously while measuring collagen output.
- Longer repair study: Draw **10-20 units** (1-2 mg) on 100-unit syringe per day or every other day for 4-8 weeks. Use 50 mg vial + 5 mL BAC = 10 mg/mL concentration.
- Topical style (research): Daily application of formulated creams or solutions in skin model experiments for 2-6 weeks.
- Higher mass vials (50-100 mg): Useful when running many cell culture plates or longer multi-week experiments.
100-Unit Insulin Syringe Conversion Chart
Reconstitution used for these calculations: 50 mg vial + 5 mL bacteriostatic water = 10 mg/mL concentration (standard for easy syringe dosing in skin research).
Important: We have already done all the math for you. U-100 insulin syringes are marked in "units" (100 units = 1 mL). Just draw the exact number of units listed below for each dose. No calculations required on your end.
| Dose (mg) | Units on 100-unit syringe (pre-calculated) |
|---|---|
| 1 mg (daily) | 10 units (0.10 mL) |
| 2 mg (higher daily) | 20 units (0.20 mL) |
These unit amounts assume the exact concentration listed above. Always double-check your own reconstitution volume against the chart.
Safe Research Cycle Guidelines
Example Cycle References from Research Literature
- Typical research cycle: 4-8 weeks on at 1-2 mg daily or every other day, followed by recovery period.
- Topical: 2-6 weeks daily application.
- Key: Follow approved protocols.
Research Notes
GHK-Cu is one of the best-researched copper peptides for skin and matrix biology. Because copper can oxidize, many labs pay extra attention to how they store and handle the mixed solution.
